Answer:

n = 7 , n = -7

Step-by-step explanation:

n^2 - 49 = 0 (Given)

n^2 = 49 (Add 49 on both sides)

n = plus or minus 7 (Square root on both sides)

Answer:  “ n  =  ± 7  ” .

_________________________________

       →  that is;   “ n = 7 ” ; or:  “ n = -7 ” .

_________________________________

Step-by-step explanation:

_________________________________

Given:

   n²  − 49 = 0 ;  Solve for "n" .

_________________________________

Add "49" to each side of the equation:

   →  n² − 49 + 49 = 0 + 49 ;

to get:

  →   n²   =  49 .

_________________________________

Now, take the "square root" of each side of the equation;

  to isolate "n" on one side of the equation;

   & to solve for "n" ;

Answer:

x=6

Step-by-step explanation:

Since the figure has 4 sides, the total of all of the angles add to 360 as:

180(n-2)=T

180(4-2)=T

180(2)=T

360=T

Now we can set up an equation and solve for x:

17x+8+74+110+66=360

17x+258=360

17x=102

x=6

So x=6

The circumference of the soccer ball can be found using the formula for the circumference of a circle, to which 10 inches is then added to find the total length of the ribbon Regina needs.

The problem involves understanding the mathematical concept of circumference. The circumference of a circle is given by the formula C = 2πr, where r is the radius of the circle. In this case, the soccer ball has a radius of 4.5 inches. Therefore, the circumference of the soccer ball would be C = 2π(4.5) inches.

Then, the problem states that the ribbon needs to be 10 inches longer than the circumference of the ball. So the total length of the ribbon that Regina needs is C + 10 inches. By substituting the values, we get the length of the ribbon needed.

Answer:

Probability of having an accident = 20% o 0.2

Thus,

Expected number of years = 1/probability of accident = 1/0.2 = 5

Hence,

3.    Every 5 years  is the correct option.

Step-by-step explanation:

The factory will expect to have an accident every 5 years.

The probability of having an accident in the factory = 20% = 20/100 = 0.2

It should be noted that the highest likelihood for an event happening is 100% which is represented by 1.

Therefore, the number of years that the factory expect to have an accident will be:

= 1 / probability of having an accident

= 1/0.2

= 5 years

In conclusion, the factory will expect an accident every 5th year.

a. It will take 1.53 seconds for the rocket to reach its maximum height.

b. The rocket will reach a maximum height of 38.04 ft (rounded to the nearest tenth).

c. The range of the function h(t) is bounded below by h0 (0 ft) and above by h_max (38.04 ft). In mathematical notation, the range is:

Range = {h | h ∈ R, h0 ≤ h ≤ h_max}

d. The maximum point on the graph of the function exists because of the negative coefficient of the t^2 term (-16).

**a. Time to reach maximum height:**

The rocket's motion can be modeled by the formula:

h(t) = -16t^2 + vt + h0

where:

* h(t) is the height of the rocket at time t

* t is the time in seconds

* v is the initial upward velocity (49 ft/s)

* h0 is the initial height (0 ft)

We need to find the time t when the height h(t) is maximum. Since the acceleration due to gravity (-16 ft/s^2) is negative, the maximum height happens at the vertex of the parabola represented by the equation.

The time to reach the vertex can be found using the formula:

t_vertex = -v / (2a) = -49 / (2 * -16) = 1.53 seconds (rounded to the nearest hundredth)

Therefore, it will take 1.53 seconds for the rocket to reach its maximum height.

**b. Maximum height:**

Now, plug the t_vertex value back into the equation to find the maximum height:

h(1.53) = -16(1.53)^2 + 49(1.53) + 0 = 38.04 ft

Therefore, the rocket will reach a maximum height of 38.04 ft (rounded to the nearest tenth).

**c. Range of the function:**

The range of the function depends on the initial parameters (velocity and height) and the gravitational acceleration. Since the acceleration due to gravity is always negative, it acts as a downward force pulling the rocket back down. This means the highest point the rocket can reach is its initial height plus the maximum height achieved due to the initial velocity.

Therefore, the range of the function h(t) is bounded below by h0 (0 ft) and above by h_max (38.04 ft). In mathematical notation, the range is:

Range = {h | h ∈ R, h0 ≤ h ≤ h_max}

**d. Reason for the maximum point:**

The maximum point on the graph of the function exists because of the negative coefficient of the t^2 term (-16). This term represents the downward force due to gravity, which continuously slows down the rocket's upward motion. Eventually, the upward velocity becomes zero, and the rocket starts descending due to gravity. This point of zero velocity corresponds to the vertex of the parabola, which represents the maximum height achieved.

The algebraic expression '3s + 2.15' can represent a real-life situation where you're shopping for food. If sandwiches cost $3 each and a soda costs $2.15, the total you'd spend on 's' sandwiches and one soda is 3s + 2.15 dollars.

Here is a scenario that could represent the expression 3s + 2.15: Imagine you're in a store and each sandwich costs $3.00. You're planning to buy 's' number of sandwiches. Now, let's say you also want to buy a soda which costs $2.15. The total cost you will spend in the store would be the cost of the 's' sandwiches plus the cost of the soda, which can be represented by the expression 3s + 2.15. So if you bought 2 sandwiches, the total cost would be 3*2 (for the sandwiches) + 2.15 (for the soda) = $8.15.

Width of the rectangle is 13 cm and length is 29 cm.

Step-by-step explanation:

Step 1:

Given perimeter of the rectangle = 84 cm. Let the width be x, then the length of the rectangle = 2x + 3. Use the formula for perimeter of a rectangle = 2(length + width) to find the dimensions.

84 = 2(2x + 3 + x) = 2(3x + 3) = 6(x + 1) [taking 3 as common factor outside)

⇒ 84 = 6x + 6

⇒ 78 = 6x

∴ x = 13

⇒ Width of the rectangle = 13 cm

∴ Length of the rectangle = 2x + 3 = 29 cm

Answer:

x = - 4, x = - [tex]\frac{1}{5}[/tex]

Step-by-step explanation:

To find the zeros let g(x) = 0, that is

(- 5x - 1)(2x + 8) = 0 ← in standard form

Equate each factor to zero and solve for x

- 5x - 1 = 0 ( add 1 to both sides )

- 5x = 1 ( divide both sides by - 5 )

x = [tex]\frac{1}{-5}[/tex] = - [tex]\frac{1}{5}[/tex]

2x + 8 = 0 ( subtract 8 from both sides )

2x = - 8 ( divide both sides by 2 )

x = - 4

Thus

smaller x = - 4

larger x = - [tex]\frac{1}{5}[/tex]

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius.

Here (h, k) = (- 2, - 1) and r = [tex]\sqrt{2}[/tex], thus

(x - (- 2))² + (y - (- 1))² = ([tex]\sqrt{2}[/tex] )², that is

(x + 2)² + (y + 1)² = 2 ← equation of circle

The measure of angle A is 88°.

Solution:

Given data:

∠A = (2x – 40)°, m∠B = 116° and ∠D = x°

A quadrilateral inscribed in a circle is called cyclic quadrilateral.  

∠B and ∠D are opposite angles in a cyclic quadrilateral.  

In cyclic quadrilateral, opposite angles are supplementary.  

⇒ m∠B+ m∠D = 180°

⇒ 116° + x = 180 °

Subtract 116° from both sides of the equation, we get  

⇒ x = 64 °

To find the measure of angle A:

m∠A = (2x – 40)°

        = 2(64°) – 40°

m∠A = 88°

Hence the measure of angle A is 88°.
